From OneUp Today
OneUp formats your post for all 9 platforms automatically — character limits, hashtag rules, link previews, image dimensions. Write once, every platform native.

Yes. Free is 280 characters. Premium ("Blue") raises it to 4,000. Premium+ goes to 25,000. Toggle the tier above the platform grid to see counts for each.
Instagram displays roughly the first 125 characters in the feed before the "...more" link. The full caption can be 2,200 characters. We highlight when you cross the visible threshold.
X's t.co shortener uses 23 characters per link in posts, but only when the post is sent. The counter shows raw character count so you can see your literal text length.
